on a digital camera,what does the funtion of white balance allow you to do?

Answer 1

Different lights have different colors, which are often described as being "warm" or "cool."

For instance:
-Tungsten Light Bulbs have an orange cast
-Fluorescent Light Bulbs have a green tint
-Sunset has an orange cast
-If you are standing near a blue building, the light reflected off of it may give the light a blue tint.
-The midday sun is typically considered "neutral" white for photographic purposes.

White balance is your way of telling the camera what the color white looks like under a given lighting condition. Your brain does this naturally: most people don't recognize the orange tint of tungsten bulbs under most circumstances. They look "normal." White balance will normalize the way the camera registers color in an image in the same way that your brain does for your eyes.

It is useful to note that your camera's flash is balanced to daylight. This is why many people's flash lit photos have very orange-colored backgrounds: the camera (by default) white-balances for the flash (daylight) when the flash is used, leaving the areas that are not lit by the flash with their tungsten-bulb color. This is why professionals carry gels in colors like CTO (color temperature orange) and window green to match the flash's light to the ambient light, allowing them to then apply a white balance to lighting of a consistent color cast. Mixed light color is *typically* the enemy for photographers.

Answer 2

Inside your camera have white balance controlling mode, but it won't given you the correct lightings,you must buy Expodisc White Balance Filter,it will given you best photos that you have taken.

Answer 3

All colours look different under various lighting conditions i.e. daylight, tungsten lamp, fluorescent lamps and candles etc. By adjusting the White balance you adjust for the light source to give correct colours to your picture.

Answer 4

like grandpa said regarding correct, however its more to do with not having a colour cast and reading of white is the most accurate because its where cast is easiest to see, for us and cameras, on broadcast TV camera one sets black balance also,


once you get it right, then you can break the rules and use a tempurature warmer or colder than the "true" tempurature

examples

1. this one is shot on 5600k daylight film (do it on digisd also) during the change of light:
